1. 0 GENERAL INFORMATION:

1.1 Purpose:

Gomco Models 270 and 2701 are portable drainage pumps designed to assure gentle suction for specialized uses as gastric lavage, abdominal decompression, doudenal and fistula drainage following prostatectomy. The suction system includes two preset drainage levels of 90mm and 120mm of mercury vacuum.

1.2 Features — Model 270:

Supplied with model 270 as standard equipment are:

1. One (1) 1200 ml glass collection container with overflow protection cap assembly.

2. One (1) wire formed bottle holder.

3. Bacteria filter to prevent fluid and aerosol contamination.

4. One disposable tubing package containing 2-six foot lengths of clear flexible PVC tubing.

5. Compact case with lighted selector switch, pump cycle light and hospital grade plug.

1.2.1 Overflow Protection:

The 1200 ml collection bottle assembly supplied with this pump includes a cap and float assembly (See Illustration No. 4). When collected patient fluids reach a predetermined level, the vacuum supply to the collection bottle is shut off by the cap and float.

1.2.2 Bacteria Filter:

The high efficiency bacteria filter is custom engineered to prevent fluid and aerosol contamination of portable suction units. This filter features a hydrophobic, microporous membrane which filters air with maximum efficiency (0.3 micron particles in air), while blocking the flow of aqueous fluids and aerosol contaminants. The Gomco high efficiency filter protects against suction pump contamination in the case of canister overflow as it helps prevent the overflow from reaching the pump.

1.3 Features — Model 2701:

Supplied with model 2701 as standard equipment are:

1. One 1100 ml disposable collection container with overflow protection cap.

2. One wire formed container holder.

3. Bacteria filter.

4. One disposable tubing package containing 2-six foot lengths of clear flexible PVC tubing.

5. Compact case with lighted selector switch, pump cycle light and hospital grade plug.

1.3.1 Overflow protection:

The 1100 ml disposable collection container supplied with this pump includes a multi-stage filter (1) hydrophobic membrane stops flow of aqueous solutions (acts as overflow protection), (2) glass prefilter allows filter to handle most laser/electrocautery applications.

1.3.2 Bacteria Filter:

The high efficiency bacteria filter is custom engineered to prevent fluid and aerosol contamination of portable suction units. This filter features a hydrophobic, microporous membrane which filters air with maximum efficiency (0.3 micron particles in air), while blocking the flow of aqueous fluids and aerosol contaminants. The Gomco high efficiency filter protects against suction pump contamination in the case of canister overflow as it helps prevent the overflow from reaching the pump.

3. 0 SET-UP:

3.1 Collection Bottle Assembly — Glass Bottle:

(See Illustration No. 4)

1. Check the bottle top edges for nicks. If the bottle top is nicked, it will not seal.

2. Check that the cap gasket is properly positioned inside the cover.

3. Check that the float moves freely.

4. Screw the cover assembly securely onto the bottle, making sure that the gasket seals.

5. Place the bottle assembly into the wire form bottle holder.

6. Connect one length of tubing, enclosed in the tubing package, to the bacteria filter and to the vertical fitting on the bottle cap and float assembly marked "to pump".

7. Connect the other length of tubing to the long bent metal tube of the cap assembly.

3.2 Collection Bottle Assembly — DCU:

1. Make sure filter shut-off is in place in under side of lid.

2. Place bottle on a flat surface and lay cap assembly on bottle. Push down on cap to snap lid to bottle.

3. Place bottle into wire form bottle holder.

4. Connect one length of tubing, enclosed in the tubing package, to the bacteria filter and to the vertical fitting of the cap marked vacuum.

5. Connect the other length of tubing to the elbow marked “patient”.

4. 0 OPERATING PROCEDURE:

(See Illustration No. 3)

1. The selector switch should be in the center "off" position.

2. Plug the line cord into a grounded electrical outlet, making sure that it is the same voltage as indicated on the unit nameplate.

3. Be sure the collection bottle is assembled properly, see 3.0, and that the length of tubing from the bottle to the bacteria filter is dry.

4. Push the selector switch on the front control panel to the desired vacuum range, up for 120mm Hg and down for 90mm Hg. The red light within the switch will remain lit indicating the unit is on.
